On one'side the drum is .proyidedivith an f opening ycontrolled byan Iadjustgllelgate10;'. Y

through. whichy openinggthe inixedjqrnateri discharge'siinto a hopperfllf'lhe bottoni' the hopperis connected-to shortxver cal* to a'horizo Slidable' inthe chalnh isfa'plutn'gerllu Vi Which-j is' connected by aT rodfl to crank ber and extending from said open end in-` wardly la certain distance are transversely spaced tapered cores 19 rigldly connected at l their inner ends to a horizontal bar 20 which extends across and is` secured tothe sidesot' thechamber.V The stroke of the plunger isso arranged that when at the limit t'its' stroke y nearest the cores, it is still some distance .inf Vwardly oithe bar 20v as shown in Fig. 3fv

From such point of limit 01"' movement of the plunger, thesides of the chamberslope inwardly tothe open end 4thereorn as shown "at Y21 in Fig. 3, so lthat the width ofsaidopen end or mouthoit the chamberfis'considerably less than the portion in which the plunger reciprocates-` -The top andbottom 'of ythe chamber, however,.are substantially parallel togeach V other throughout their extent. The

Y, cross `sectional form and size ofthe tile is 'areaof the mouth of the chamber though considerably smaller than the plunger containing portion is somewhat larger than the end area of the tile to be formed.. The exact A therefore gauged by wires22 disposed a short distance outwardly ofthe chamber and arranged in. rectangular form, and past which the material is pushed when being forced from the chamber.-

The operationv of the machine is as follows During the back stroke ofy the plunger, the chute 12 is uncovered, and thematerial from the hopper 11 `falls into the chamber 13.

Y With the forward stroke of thevplunger the chute is covered and the material previoL `1l 4d *i os't din Vthe vchamber is moved s y ep 1 e carriage; the shelf also having shallow side alongandforeed into the rrestricted mouth area, the restriction of kwhose area is of course lncreasedloyl the presence of the cores;

As a result the material `issues from the mouth in a highly compressed state vas is necessary toformrthe tile. The forward stroke of the plungerl being `terminated ahead of such restricted.area,.the material in the chamber immediately ahead of )the plunger, is not compressedto any extent but is still; in a loose state. Therefore, with a subsequent complete reciprocation of the plunger, the new charge'of material depos-y ited in the chamber from the hopper and engagedby the plunger on its J,forward stroke,

become's thoroughly merged and intimately mixed with the material already in the chamber between the plunger and the cores.

' This as will be'evident avoids the possibility of a poor bond being had between the initially separated charges of material.v As av result the formed and compressed material issues from theV machine in an unbroken length oi thoroughly knitted and homogeneous character as shown at 23,'and it is only necessary to cut this material into the lengths to form the tile units 24:.

To accomplish this the following structure is associated with the forming machine: The formed material' as discharged from the presser chamber is received onto a stas tionary' table along which Vthe material slides. A carriage 26 is mounted in longitudinally slidable relation with and under lthe table, said carriage alsoy having a table 27 disposed immediately under the table 25'. Mountedonthe carriage beyond thetable 27 is a rotatable tilemsupporting spider. This spider comprises a central hubZS on'which is lined a number' of shelvesi/Q, each of sutlicientlength to support aptile for the full lengththereof. 1 These shelves are not radial with thev axis ofthe hub but are tangential proper thereto andsomedistance froml the axis thereof, The 'shelves are also disposed at right .angles to each other. i The shelves `are arranged tolongitudinally aline with and face the table in successive order, and when one is Vso alined it is above the axis of the hub, being adapted to move upwardlyV from` such position withthe rotation ofthe spider.v Any shelf when in the above posi-` tion is held from, dropping by means'ot a; laterally yleldable spring supporting me1n-.

ber 30which is mounted onandprojects upwardly from the carriage.

The continuous length ot formedv material flanges projecting upwardly therefrom` as shown. The continuous strip or length of materlal 1s then cut through toV form the in vdividual tile'by the following means:

- Upstanding 'from the carriage on each side and ahead of the spider are posts 32 on which a frame 33 is vertically slidable. This frame supports a severingwire 34 which. is disposed,

litt

in a transverse vertical plane between the 1 a end ofa horizontally disposedspider shelf and the adjacentend of the table 25 and is set at an angle to a horizontal plane. The frame 33 is provided with laterally projecting handle bars 35 so that it may be pulled down to cause the wire to cut through the material, and spring means 36 may be provided f desired .to vraise the frame'from its y lowered position.

I agrip on the en dof the tile willnot tend to cause the same to sag ,between itsends asy would bethe case ifV it were lii'tedfrom a `.tion and the table 25, it willbe' seen that as? the spider is rotatedto raisea' tile after the' same has been cut,' it s cutedgemoves quickly .away from the remaining Vso that there is fno chance mass on the table, jfqr the edgesiust cut thronghto pull' against-'each other` andv Vftend to distort the; still plastictile olf-damage j the clean cut originally inade. .f1 VVhenf the tile is'raised to' a vertical'position Vbyxtheroflotation oir' thefspider, it'will be Ystill supportedagainstbuckling or. warping and `in a posi-` tion to be then raised and removed by handean operation' which being accomplished by `horizontal position.

Y The sliding of thecarriage (which is had by the ypush of the iadvancing zmaterial against the upstandingjspider shelf)v enables such advance to continue some distance even after the material actually abutsV against the turned to its'originalposition by hand after Vfrom so that 1 This avoids the necessity of exactly timing i' the cutting operations to'ythereciprocations and also avoids the possibility5- of the plunger, of the material buckling as .might be the case if the spider was immovably mounted relative to thetable 25. "The" cutter being mountedfon the carriage-moves with the spiderl vand is always the same distance therethe-tile will always be cut to the same length, andsuchcnttin-g operation may be carried out even though the carriage is ac# f tually being moved at the time; Afterthe i carriage is thus moved,it"is "of course yrea cut tile has been raised andanotherspider sheli'has been moved toa horizontal position to receive thecontinuouslyI advancing ma- Y terlal'.`
